The instrument I think of when I think of the ocean is the sextant, presumably from old movies. I am familiar with most of the names you mentioned though, some from drafting.
As you say, it would be crazy to rely solely on electronics, but check out the number of times Search and Rescue gets called for people that thought they could head out into the back country with only their phone. It's ridiculous how much people trust a device.
